Do you know what precision machining is?

What is fine machining? What is mainly used for processing and what are the requests for information? The processing accuracy is more accurate than ordinary machinery, reaching and exceeding 0.1 micron machinery belongs to fine machinery. Usually fine machining is the use of fine machine tools and fine measuring tools and meters in the strictly controlled environmental conditions down to complete. Can be used in the aerospace industry hydraulic and pneumatic servo mechanism of the fine coordination parts, gyroscope frame, shell, air float, hydraulic floating bearing components and float, etc. Data on fine machining are divided into two categories, metal data and non-metal data.

 What is the request for information about fine machining? Not all materials are suitable for fine parts processing, about the metal data, the hardness in order for stainless steel, cast iron, copper, aluminum. The processing of ceramics and plastics is the processing of non-metal data. Limited to the hardness request of processing parts, in some places, the data is the higher the hardness value, the better, but the processing data can not be too hard, otherwise it can not stop processing. So according to the function of the processing of devices to the reasonable selection of materials, ordinary places, the material is best moderate soft and hard applicable.

Before stopping the fine machining, it is necessary to pay attention to the density of the selected material (hardness), if the hardness has exceeded the hardness of the parts (lathe car knife), not only can not be processed and may damage the parts or form a risk, for example, in the past there was a car knife falling into hurt people and other things. Therefore, for mechanical processing, the data material must be lower than the hardness of the machine knife, so that it can be processed.

Fine machining mainly has refined car, boring, milling, grinding and grinding process. The effect presented by: the boundary or characteristic size tolerance of the parts is below the micron; the geometric shape and mutual position accuracy reach the micron or angular second level; the outer micro undegree is less than 0.1 micron; the mutual fittings can meet the request of coordination force and accurate mechanical or other physical characteristics.
